Abstract
The invention discloses a disc-type double-shaft solar tracker comprising a photovoltaic module and a mounting platform used for installing the photovoltaic module, wherein the center of the mounting platform is provided with a spindle and tracks the solar azimuth of the photovoltaic module by rotation; the mounting platform is provided with a bracket array, the photovoltaic module is installed on the bracket array, and the bracket array of the photovoltaic module is connected with a transmission mechanism for regulating the pitch attitude of the photovoltaic module. Compared with the prior art, the photovoltaic module of the invention is installed on the bracket array and is arranged in row, and the overall height of the photovoltaic module is greatly lowered, thus lowering the centre of gravity of the mechanical structure of the tracker, increasing overall stability and reducing overturning moment. A solar panel is split on multiple groups of small brackets to avoid generating huge and continuous wind receiving faces, and a larger gap is naturally formed between groups, which is favorable for wind to pass, prevents wind power from accumulating and effectively improves wind resistance capability.
Description
Technical field
The invention belongs to solar tracking equipment, relate to the improvement of solar tracking device structure mode.
Background technology
Existing large-sized double-shaft sun tracker, its form mainly contain forms such as T type (pillar), V-type, rail mounted.All be that photovoltaic module is installed on the whole framework, make photovoltaic module form a bigger plane or almost plane, and this photovoltaic module installed surface is supported to higher position by the supporter that certain form is set, for the photovoltaic module installed surface provides rotation required space, wherein the supporter of T type is a column, and the supporter of V-type is " V " font or the up big and down small support frame that is similar to the inverted triangle shape, and the slew gear of supporting the position angle to follow the tracks of is arranged on top, the following or stage casing of supporter.Rail mounted then uses the up and down approaching supporter of size, and the slew gear of supporting the position angle to follow the tracks of be a series of wheel then, and circle or arc track is set with the motion that guides wheel and then realize azimuthal tracking.
Present existing large-scale sun tracker because its main thought is that all component is installed on the big framework, and is lifted to certain height with it so that the enough revolution spaces of its acquisition with corresponding supporting construction.The easy like this installed surface scale of construction that causes is bigger, in strong wind weather, forms a bigger windward side easily, and the easy more continuous accumulation that causes blast in big more windward side, and then causes the physical construction load of tracker to increase, and causes damage easily.Although a lot of trackers can be set level installed surface and the wind comes to reduce destruction to avoid the front under bigger wind speed, but the direction of wind is unfixed often, and wind is excessively behind the photovoltaic mounting plane of level, can form uneven pressure field thereon down, cause significantly rocking of photovoltaic installed surface, cause the fatigue of materials of supporting construction or power push-rod to cause fracture easily.And big more installed surface needs photovoltaic module is rotated required space to high more height with acquisition by support structure elevates more, and wind-force often hoists bigger and bigger, and the wind load of generation is also big more.And supporting construction is high more, and the moment that stressed back, its top produces is big more, needs to increase the material input more and overcomes, and causes the increase of cost.
Summary of the invention
Technical matters to be solved by this invention is at above-mentioned the deficiencies in the prior art, and the disc type that a kind of wind loading rating is strong, resistance to overturning is good biaxial solar tracker is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of disc type biaxial solar tracker, the mounting platform that comprises photovoltaic module and be used to install described photovoltaic module, the center of described mounting platform is rotating shaft and the tracking that realizes the photovoltaic module solar azimuth by rotation, it is characterized in that: described mounting platform is provided with the support array, described photovoltaic module is installed on the described support array, is connected with the gear train that is used to adjust the photovoltaic module pitch attitude on described support array.
Be provided with rolling mechanism in described mounting platform lower end.
Round, the annular or fan-shaped of being shaped as of described mounting platform.
Compared with prior art, advantage of the present invention is:
Adopt the disc type mounting structure, can increase substantially the unit installed capacity of biaxial tracker, and and then reduce the quantity of control gear.
Photovoltaic module is installed in photovoltaic module and installs on the array, so arrange that in a row the whole height of photovoltaic array greatly reduces, and can reduce the center of gravity of tracker physical construction, increases resistance to overturning, reduces tilting moment.
Do not need the assistance of hoisting device in the installation process, reduce installation cost.
But maintenance and maintenance all manpower are finished, and effectively reduce and safeguard and operating cost.
Solar panel is divided on a lot of groups of small racks, avoids producing huge continuous wind surface, and can form big slit by nature between between the group, help passing through of wind, prevent the accumulation of wind-force, and can effectively improve wind loading rating.
Even solar components or mounting structure are to be damaged under extreme wind, its damage situations also can take place in indivedual groups, can not cause toppling or destroying of overall optical volt installed surface as traditional photovoltaic tracking device, thereby reduce failure rate, the utilization factor of raising assembly.And because center of gravity reduces (generally caning be controlled in below 2 meters), even assembly is blown off by extreme wind, also be not easy to break, effectively prevented to cause big economic loss because of assembly damages.
A kind of assembly installation method of biaxial solar tracker is characterized in that: assembly is installed with little array combination, and by a plurality of little arrays being set to realize installing the expansion of the scale of construction, to realize low dwarfing, the flattening of tracker.
Photovoltaic module is installed in photovoltaic module and installs on the array, provides support with the array of a plurality of little scale of constructions, and the weight distribution that makes whole tracker is on a plurality of arrays basis.
By grouping solar components is installed, is reduced the front face area in the single group, and have passing through of bigger space permission wind between group, prevent bigger windward side continuously, avoid the accumulation of wind-force.
The installation of photovoltaic module is not to be on unique plane, but is divided into some groups, and is installed on the lower load plane.Avoided and be must the hoist structure of lifting of the revolution space that satisfies the photovoltaic installed surface, effectively reduced the center of gravity of tracker, reduced tilting moment, improved tracker stability.
